The Drama Between Kim Kardashian West and Her Ex Assistant & BFF Steph Shepherd Heats Up

The drama between Kim Kardashian West and her former assistant (and best friend) Stephanie Shepherd is heating up.

Last week, Kim fired Steph after working together for over a year, and becoming close as they shared vacations and time together as a 'family.'

"Kim made a decision to let Stephanie go," a source told PEOPLE magazine. "She was a good assistant but when Stephanie wanted to transition into a larger role with Kim's brand and businesses, it just didn’t work. Kim gave her the chance but after a short period of time it became clear that Stephanie just didn’t have the knowledge to take on a role like that. Kim made an executive decision to part ways."

The source adds, “She’s still friendly with the other sisters but she and Kim aren’t really speaking.”

The fact that the pair haven't been speaking has become clearer in the last couple of days. Steph posted a message on her Instagram Story, which fans believe is her way of throwing shade at Kim.
